More than 500 of them have been stolen from Cumberland Farms stores in several states in recent months, reports AP.

The signs promote iced coffee dubbed "Iced Hoffee."

And now, the thievery has left a convenience store clerk critically injured.

Authories in Shelton, Conn., say a clerk working at a Cumberland Farms store saw a man and two women put two life-size cutouts of the Baywatch star into an SUV shortly after 1 a.m. Tuesday, reports CTpost.com.

Police say the clerk was struck and dragged by the SUV before landing on his head. He is hospitalized in critical condition, and authorities are looking for the suspects.

The signs were really popular last year when the campaign first broke. This year, the company ordered extras as a "substantial buffer, just in case," the chain's vice president of marketing, Gwen Forman, told the Boston Business Journal in June. And Hasselhoff recorded a music video ad titled Thirsty For Love. The song might not have taken off, but the signs have.
